Answer choices

  1. Too Strong: can never be explained3% picked this

    language acquisition can ever be fully

    This sounds like too fatalistic a question: "Sigh, so if it's a mix of both environmental and innate factors, then can we really ever fully explain it?" Law school applications are a mix of GPA and LSAT factors. Does that leave us helpless to ever fully explain law school applications?

  2. Already Stated19% picked this

    innate mechanisms are a contributing factor in

    The author just told us that innate mechanisms are a contributing factor. She said "innate mechanisms also play a role in language acquisition". It would be silly to say, "Ben is a fan of hockey. So, the most reasonable question that ought to be studied is whether Ben likes hockey."

  3. Contradicted / Too Strong: solely2% picked this

    language acquisition is solely the product of

    The first sentence says that we have revealed facts about the influence of environment on language acquisition. The author is saying that environment isn't the only influence, but it's definitely still an influence. So it's contradictory to say that language acquisition is only influenced by innate mechanisms.

  4. Too Strong: the most1% picked this

    parents and peers are the most important influence on a child’s learning

    We would have been happy with an open question like, "Whether environmental or innate influences are the more important" But there's no reason we'd expect this paragraph to be leading to a very specific question about whether two types of environmental influences (parents and peers) are the most important influence.

  5. Correct77% picked this

    innate mechanisms play a more important role in language acquisition than a

    Why this is right

    The two setup thoughts were, - environment plays a role in language acquisition - innate mechanisms also play a role This question is a safely worded blend of the two. We know that language acquisition is a blend of these two types of influence, so let's study which one plays a bigger role.
